Andrew Tridgell	48247b6adc	HAL_PX4: minimise usage of hrt_absolute_time()	11 years ago
Andrew Tridgell	1241da466b	HAL_PX4: added millis64() and micros64()	11 years ago
Andrew Tridgell	849c4905fb	HAL_PX4: print overtime message on stuck task this should make it easier to narrow down stuck task bugs	11 years ago
Andrew Tridgell	bf2dd141e9	HAL_PX4: support uartE for 2nd GPS	11 years ago
Andrew Tridgell	0b25ff0a16	HAL_PX4: added uartD	11 years ago
Andrew Tridgell	8dc6b758f3	HAL_PX4: switch to delay_microseconds_semaphore() for UART timer this may prevent some timing jitter on the GPS UARTs	11 years ago
Andrew Tridgell	5800c2a2c8	HAL_PX4: prevent excessive writes on startup from blocking this could cause copter on PX4 to hang on startup	11 years ago
Andrew Tridgell	622f0dcc1d	HAL_PX4: prevent threads running before subsystems are initialised this fixes a bug where the timer thread would hang waiting for the console on startup. This caused the "hit enter" behaviour with recent PX4 bugs, as AnalogIn tried to read from fd==0, which was a console read	11 years ago
Andrew Tridgell	1c091cbca5	HAL_PX4: fixed a scheduler bug that affects UART IO we need to detect if we are in a timer task using a PID, not a flag. This is the same type of bug I fixed last week, but now fixed properly. The bug could well be the "USB bug" that Craig has been chasing	11 years ago
Andrew Tridgell	d973730b88	HAL_PX4: use hrt timer and semaphores to improve timing this gives much more accurate microsecond delays, while also ensuring we yield the CPU when possible	11 years ago
Andrew Tridgell	63bee0b2d8	HAL_PX4: disable checks for in_timerprocess these are not valid in this form for the way the timer thread works on PX4.	11 years ago
Andrew Tridgell	67db1cedaa	HAL_PX4: fixed delay_microseconds() on PX4 we could underflow and delay a very long time!	12 years ago
Andrew Tridgell	942ae70651	HAL_PX4: updates for AP_HAL::MemberProc	12 years ago
Andrew Tridgell	7ec242146d	HAL_PX4: update for new scheduler API	12 years ago
Andrew Tridgell	fb56feb6b2	HAL_PX4: support all analog input pins, with scaling this allows voltage/current/Vcc sensing on FMUv2	12 years ago
Andrew Tridgell	fa107bdb58	PX4: moved UART handling to its own thread this prevents slow writes to the SD card from interfering with MAVLink or GPS serial communication	12 years ago
Andrew Tridgell	7082e0f8aa	AP_HAL: added hold_in_bootloader parameter to scheduler->reboot()	12 years ago
Andrew Tridgell	e5f19e314d	PX4: systemreset() now takes a boolean argument this chooses whether to stay in the bootloader	12 years ago
Julian Oes	56e94d70e9	PX4: Adaptations to latest build changes	12 years ago
Andrew Tridgell	af7381e9e0	AP_HAL: added register_io_process() this is used to register a low priority IO task. Used for file IO in DataFlash_File.cpp	12 years ago
Andrew Tridgell	8e2a20bea8	HAL_PX4: enable ttyACM0 as main console, ttyS1 as telemetry port	12 years ago
Andrew Tridgell	02b4ecc273	HAL_PX4: get RC input from PX4IO board this allows us to support DSM and SBUS receivers	12 years ago
Andrew Tridgell	8f2f4b1bc5	HAL_PX4: use write() to /dev/pwm_output for servo output this lowest the cost of PWM output a lot, but relies on the new I2C based IO firmware	12 years ago
Andrew Tridgell	70227d5d93	HAL_PX4: added scheduler performance counters	12 years ago
Andrew Tridgell	966b9b9b9c	HAL_PX4: format panic messages with a newline	12 years ago
Andrew Tridgell	952df2fced	HAL_PX4: new buffered storeage driver for microsd cards this does all IO in the timer thread, avoids writes that don't change data, and does all writes in multiples of 128 byte chunks. This should be about as friendly to SD cards as we can get.	12 years ago
Andrew Tridgell	2a10727902	HAL_PX4: run timer thread as SCHED_FIFO this ensures it never yields to the main thread, which would break our locking assumptions	12 years ago
Andrew Tridgell	6ffa18fa61	HAL_PX4: rewrite UART driver to be much more efficient this does the IO in the timer thread, and uses buffers in the main task to avoid system call costs in the flight code. The cost of PX4 read and write system calls is quite high - about 10 to 15 usec. We can't afford to pay that per byte	12 years ago
Andrew Tridgell	39e28d48c2	HAL_PX4: switched scheduler to use a pthread this allows the timer tasks to access file descriptors in the main APM task, which makes writing PX4 device drivers much easier	12 years ago
Andrew Tridgell	7c7a215934	HAL_PX4: fixes for new Scheduler API	12 years ago
Andrew Tridgell	5829d44a22	HAL_PX4: disable failsafe handler this won't work until we can set RC output values in timers	12 years ago
Andrew Tridgell	9f423a24ad	HAL_PX4: yield CPU in delay() this allows other apps to run	12 years ago
Andrew Tridgell	1e69b88261	HAL_PX4: use write() in panic() this allows panic from the UARTDriver	12 years ago
Andrew Tridgell	b30fa6535b	HAL_PX4: support reboot	12 years ago
Andrew Tridgell	c6305b5876	HAL_PX4: rework Scheduler using hrt calls thanks to Julian Oes for the suggestion	12 years ago
Andrew Tridgell	5053fb8acc	HAL_PX4: implement atomic operations	12 years ago
Andrew Tridgell	5a70f3becf	HAL_PX4: added a scheduler implementation	12 years ago
Andrew Tridgell	93040e5725	AP_HAL: removed the defer_timer_process() function this is now unused	12 years ago
Andrew Tridgell	60d3df50ae	AP_HAL: changed delay() to take a uint16_t this allows for up to 32 second delays, and saves a bit of flash space	12 years ago
Pat Hickey	4c715bfd04	AP_HAL_AVR_SITL: add Util driver, fix deprecated deps on HAL_AVR.h	12 years ago
Andrew Tridgell	dcc17dad94	SITL: added panic() method in scheduler	12 years ago
Andrew Tridgell	8916b280fd	SITL: filled in more of the HAL SITL backend	12 years ago
Andrew Tridgell	d42cbb791f	HAL_SITL: start filling in more of SITL framework	12 years ago
